Rolling storage inside a fixed frame is what makes this slim cabinet work: a 16.5 by 6.3 by 15.5 inch cart slides out on casters at the base, so bottles kept at floor level come to you. Above it, three open shelves with 9.5 inches between them keep daily items visible, and a pull-out drawer measuring 13 by 4.5 by 3.5 inches inside hides the small things. The whole unit is 18 by 8 by 45 inches, narrow enough for the gap between toilet and sink, and holds 66 lbs while weighing 27 lbs. White MDF panels wipe clean after splashes, and the cart can be rolled to wherever you are cleaning and pushed back afterwards. Assembly is required, and the raised shelf edges stop bottles rolling off when the cart is pushed back in.
